Application filedJ'uly 9, 1908. Serial No. 442,716. I

To all whom it may concern:

Be it known that I, HARVEY W. CURTIS, a citizen of the United States,residing at Chicago, in the county of Cool: and State of Illinois, haveinvented certain new and useful I Improvements in Fumigators';'a'nd I dodeclare the follow-111g to be a full, clear, and GXM act description ofthe invention, such as will enable others skilled in. the art to whichit appertains to make and use the same. I

This invention relatesto improved fumi= gators or disinfectantgenerators. The object of the invention is to rovide a simplyconstructed and effective "umigator fordisinfecting purposes. f W hthese and other objects in view, the

invention consists of certain novel features of construction;combination and arrangementof parts, as will be more fully described andparticularly pointed out in the appended claims.

' stop for preventing lateral moveinentot' the lamp which it is designedto hold;

The lamp here shown is made in the form of-a cupshaped receptacle havinga plu rality of spaced openings 5, formed in the upper portion of thebody thereof to permit the access of air to the flame. This lamp may beprovided with any suitable wick holding.

means arranged in the bottom thereof, paraflin l being used with awick'l su ported therein and the upper edge'of the amp is adapted to beconnected with the disinfectant containing vessel, now to be described.

The containing vessel, as shown, comprises closed receptacle 6, havingan opening 7, in the top thereof provided with a suitable closure,-suchas a cork or any other suitable device. This receptacle '6, is providedaround the lower end thereof with a trough 8, for holding water. Agroove or socket 9, extends around the bottom of this receptacle toreceive the .l'upper edge of the cup-shaped lamp member 4,-by means ofwhich said receptacleisfsupported above the flame of the Ition, the fireproduced by the lamp 4 serves lamp in position to be heated thereby. TheI I trough 8 is )referably made separable from the receptac Gand has anoffset annular portion 8 to form the lamp receiving groove or socket 9.1 I

In the use of this device, a suitable volatile disinfectant such as anaqueous solution of formaldehyde, is first placed within the re ceptacle6, and the opening -7 therein isclosed until the device isready to beused. Water is first placed in the lower plate or tray 1', say, aboutone ounce and the trough 8, is also filled with water. The closure isthen removed from the opening 7, and about one ounce of water is pouredinto the container and the wick of the lamp is then lighted and thedevice is left in the room to be fumiga'ted,'the transoms and allopenings having first been tightly closed. The room is then left closedfrom fiveto ten hours, the longer the better, and when opened all. germscontained therein will have been destroyed) By constructing the trayl asshown with an upturned flange 2, two spaced water reservoirs areprovided which provides for the use of a large qluantity of waterthereby increasing the v0 ume of vapor. r

In using formaldehyde as a ger-iiii'cid'e, it is essential thatformaldehyde vapor be produced and that thatsvapor be raised to thehighest temperature it is )ossible to obtain in order that it may havethe necessary pen'e-' trating power and, byapplicants construcnot onlyto heat the cup 6. but also to heat the'water in the reservoirs formedby the tray land the trough 8 causing the water to evaporate and producethe necessary vapor.

This device is simple and eflicient'and by placing the water in the trayand in the trough of ther receptacle all danger of'fire is obviated. Thelamp is preferably rovided with a wick in the center thereof raving apredetermined amount of 'parallin placed therearound adapted to burn fora certain length of time after which the fiaine will be extinguished,and this form of lamp renders the device very safe. i 7

'From the foregoing description taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the invention, claims.

I claim as my invention:

1. A iumigating device comprising two vertically spaced Water troughs, alamp arranged l Ween said troughs with the heating portion thereof inclose proximity to both of said troughs to quickly heat the Watertherein, and a disinfectant containing vessel supported above said lampadjacent to the upper trough and in the path of the vapor rising fromboth of them.

2. A fumigating device comprising two vertically spaced annular Watertroughs, a lamp arranged between them and support- .mg the upper trough,and a disinfectant contaming vessel supported by said lamp within saidlipper trough.

3, fumigating device comprising a closed vessel having an opening in itsupper end and a trough extending around the lower end thereof, saidtrough having a groove extending around its inner face, a lamp havingits upper edge adapted to detachably engage said groove forsupportingthe trough and vessel above the lamp and a Water containingvessel arranged around the base of said 4. A devi e of the classdescribed comas defined in theappendedprising a closed vessel having anopening in its u per end, and a trough extending around the ower endthereof, said trough having a groove extending around its inner face,and a lamp having its upper edge adapted to detaohably engage saidgroove for supporting the trough and vessel above the lamp.

5. A 'l'umigator comprising a base plate having an upturned flangeextending therearound to form a water trough, a cup-shaped lamp havingopenings in the side Walls thereof near its upper end, and a closedvessel or the disinfectant provided with means for detachably engagingsaid lamp and supporting said vessel thereabove, and a water trougharranged around the bottom of said vessel.

6. A l'umigating device comprising two vertically spaced water troughs,a lamp arranged between said troughs and supporting the upper trough,and a disinfectant-containing vessel supported by said lamp ad ja' centsaid upper trough.

In testimony whereof l have hereunto set my hand in presence of twosubscribing witnesses.
